2) Annd why not Alter? Of course you don't have to draw him with that... Dress with tendrills?! (I don't even know what is that.), but if you prefer, you may do that too ^^ feel to draw him how you prefer.

Well I have also some clothes ref that isn't normal, but they're all similiar to: fav.me/d6va28g and I think it may a bit too complicated XD well I let you decide what to do.

And the custom you may do something creepy if you can c: or if you're not much into dark or scary stuff even something cute is ok ^^ preferable something human or humanoid, avoid animals XD I can't draw them at all yet.

Oh btw the drawings can be of anything and it can e in color or pencil shaded. Just letting you know pencil shaded will be better cuz I'm just learning color xD but they won't be sketches, unless you want them to be sketches? :3
